ENH: Support linking to shared libs with dependent libs
- Split IMPORTED_LINK_LIBRARIES into two parts: IMPORTED_LINK_INTERFACE_LIBRARIES IMPORTED_LINK_DEPENDENT_LIBRARIES - Add CMAKE_DEPENDENT_SHARED_LIBRARY_MODE to select behavior - Set mode to LINK for Darwin (fixes universal binary problem) - Update ExportImport test to account for changes
